Why the pair
Equity says what was produced; drawdown says what it cost.
An equity placement is a statement about output with no price attached. The system could have reached P70 by operating exactly as modelled, or by consuming risk the model never authorised, and the equity band is identical in both cases. The drawdown placement supplies the missing half — the risk actually spent producing that output, located against what governed futures spend. Only the pair describes a transaction. This is the same principle as the conversion rows in the comparison stack, applied at the level of the two headline distributions, and it is why the standard states flatly that a strong equity result with abnormal drawdown is not clean alpha.
Schematic percentile placements. The equity bar alone would rank these months A, B, D, C — the pairing reorders them entirely, and only D describes a system operating as designed.
